2017 Year-end analysis of racing in MABRA

This post is just an advertisement for the 15th edition of my year-end analysis of bicycle racing in MABRA. You have to get the full (47 page) report on-line: Link to PDF

Some visually interesting plots from the report appear below. 
Distribution of ages of all racers in USACycling.

USACycling membership since 1970.
Attendance at popular MABRA criteriums since 2012.
Racer retention in the US. Plot shows the fraction of racers remaining as a function of the number of years since they first took out a USACycling license.
